Question

A company is developing a new system that will unlock a computer automatically when an authorized user sits in front of it, and then lock the computer when the user leaves. The user does not have to perform any action for this process to occur. Which of the following technologies provides this capability?

  • AFacial recognition
  • BFingerprint scanner
  • CMotion detector
  • DSmart cards

Why each option

This question identifies the biometric technology capable of automatically unlocking a computer upon an authorized user's arrival and locking it upon their departure, without requiring any manual user action.

AFacial recognitionCorrect

Facial recognition technology uses cameras to continuously monitor the user's presence. When an authorized user's face is detected in front of the computer, the system can automatically unlock, and conversely, it can automatically lock the system when the authorized face is no longer detected, requiring no explicit action from the user.

BFingerprint scanner

A fingerprint scanner requires a user to actively place their finger on the sensor, which constitutes a user action and does not enable passive automatic locking or unlocking.

CMotion detector

A motion detector can sense general movement but cannot identify a specific authorized user, thus it cannot provide secure, personalized automatic unlocking or locking.

DSmart cards

Smart cards require a user to physically insert or tap the card into a reader, which is an explicit user action and not an automatic, passive process.
